These two pictures, taken by Hawaii County Civil Defense, show some of the work of the Lava flow that threatens Pahoa. It moves slowly but inexorably in many directions.
In the picture on the left one can see a small pond past the transfer station and across the road from it. The only house that has burned so far stood on its banks to the right. So far the town and the highway have escaped the flow but just barely.
The picture on the right is of the lava stacked up behind the chain link fence that surrounds the transfer station but the lava has already breached it in several places and if it continues will destroy the fence and reach the transfer station buildings. The fence as you can see is already giving way.
